What is the probability that at least two of the coins will be tails?

Respuesta :

Answer:

1/2

Step-by-step explanation:

if you count how many it is 4/8 but when simplified 1/2

The probability that at least two of the coins will be tails is 3/8

What is probability?

Probability is the likelihood or chance that an event will occur

The formula for finding probability is expressed as:

  • Probability = Expected outcome/Total outcome

The total outcome of three dice tossed is expressed as [tex]2^n[/tex] where n is the number of tossed dice.

  • Total outcome = [tex]2^3=8[/tex]

If the dice are flipped and  at least two of the coins will be tails, the expected outcomes are:

  • Expected outcome = (THT), (T,T,H) and (TTT) = 3 outcomes

Pr(at least two of the coins will be tails) = 3/8

Hence the probability that at least two of the coins will be tails is 3/8
